- HANDLE FOR FILES AND OTHER TOOLS.

SPECIFICATION forming part of Letters Patent No.` 288,047, dated November 6, 1883.

Application inea' september e4, isles. (No man.)

To all whom t may concern:

Beit known thatl, J osiAH F. FRENCH, a citizen oi' the United States, and a resident of Philadelphia, Pennsylvania, have invented certainlmprovements in Handles for Files and other Tools, of which the following is a specification.

My invention relates to that class of tangs and handles for liles and other tools in which the handle is furnished with a threaded nut adapted to a threaded tang; and my invention consists, mainly, of the combination of a file or other tool having a tapering tang and a tapering thread thereon, with a handle provided with a nut having a tapering internal thread,

to correspond with that on the tang, substantially as deseribed hereinafter.

In the accompanying drawings, Figure 1 shows the handle and tang for files and other tools, the handle being in section; Fig. 2, a transverse seetionon the line l 2, Fig. 1; Fig.' 3, an enlarged view, showing the thread on the tang and nut; and Fig. 4, a view illustrating a modication of my invention. j

' Referring to Figs. 1 and 2, A is the tapering tang of a file or other tool, thistang being ofthe usual tapering wedgelike form, suitable to be driven into the wood of an ordinary handle when the special handle shown is not at hand. IIhe tang, however, has a tapering thread, a, formed on its opposite edges, and this is adapted to a'corresponding tapering internal thread in a nut, b, which is driven into the w'ooden portion of the handle, and is six-sided, or otherwise formed to preventit from turning. f The handle has a ferrule, d, the outer end of which, in the present instance, Yis bent over the ilanged end of the nut, a feature claimed in the application filed by me August- 24, 1883, Serial No. 104,634, allowed September 12, 1883, and therefore disolaimed here. The handle is screwed onto the tang until the tapering thread of the nut has a firm bearing on lthe thread of the tang, when the handle will be firmly secured to the iile or other tool. It will be understood that the orifice e in the handle is of such size that the tang shall present no obstruction to the free turning of the handle in securing the same tight to the bearing.

A nut with a tapering internal thread Amay be secured to the handle in ways other than than that shown. It may, for instance, be

with that of the nut. I prefer, however, to

locate'the nut at the end ofthe handle, as shown in Fig. 1, so that the plain portion of the tang may be of considerable length for being driven into the wood of an ordinary hant dle when no special handle is at hand. It may be remarked, however, Vthat if the edges of the thread on the tang do not protrude beyond the plain nnthreaded edges of the same (see enlarged view, Fig. 3)A the said thread will t not materially interfere with the driving of the tang into a Common handle.

In the modiiication, Fig. l1, the tapering end of the tang is Contained in areoess in a block, m, which is at liberty to slide in the oriiice of j the handle, so that it will accommodate itself to the length of the tang, a spiral spring, n, being interposed between the end of the ori-V ice and the block, an d foroin g the latter against the tang, which it tends to so retain laterally j Vthat when the blool; is used the thread on the tang andwin the nut may be much shorter than is shown in the drawings.

I disclaim the tang with a tapering thread, separately considered, as it is shown in the application led by me September 18, 1883, Serial No. 106,695.

I claim as my invention- 1. The combination of a file or other tool having a tapering tang and a tapering thread thereon, with a handle provided with a iiXed nut having a tapering internal thread to oorrespond with that on the edge of the tang, substantially as set forth. Y

2. The Combination of the threaded taperg ing tang of a iile or other tool with a handle having a nut adapted to the tang, a sliding block, m, recessed to receive the end of the tang. and a spiral spring interposed between the block and the end ofthe orice in the hang dle, substantially asV described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

.IOSIAH F. FRENCH.
